Protecting the environment
General notes
H Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in am anner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors: R
operating condition sofy our vehicleR
your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions: R
avoid short trips as these increase fuel con-
sumption. R
always make sure that the tire pressures
are correct. R
do not carry any unnecessary weight. R
remove roof racks once you no longer need
them. R
ar egularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals. R
always have service work carried out at a
qualified specialist workshop.
Personal driving style: R
do not depress the accelerator pedal when
startin gt he engine.R
do not warm up the engine when the vehicle
is stationary. R
drive carefully and maintain as afe distance
from the vehicle in front. R
avoid frequent, sudden acceleration and
braking. R
change gear in good time and use each gear

The tires should always be inflated to the rec-
ommended tire pressure. R
Remove unnecessary loads. R
Remove roof rack sw hen they are not needed.R
Warm up the engin eatl ow engin es peeds.R
Avoid frequen ta cceleration or braking.R
Have all maintenanc ew ork carried out as
indicated by the servic ei ntervals in the Main- tenance Booklet or by the servic ei nterval dis-
play.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
G WARNING
Drinkin ga nd driving and/or takin gd rugs and
driving are very dangerous combinations.
Even as mall amount of alcohol or drugs can

ing drugs.
Emission control
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Therefor en ever leave
the engin er unning in enclosed spaces with-
out sufficien tv entilation.
Certain engin es ystems are designed to keep
the level of poisonous component sine xhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications .A lways have
work on the engin ec arried out at aq ualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
Ben zC enter for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at aq ualified specialist
workshop.
The engin es ettings must not be changed under
any circumstances. Furthermore, all specific
servic ew ork must be carried out at regular
intervals and in accordance with the Mercedes-

Brake fluid
G WARNING
The brake flui dc onstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low ,v apo rp ockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is ar isk of an accident.
You should have the brake flui dr enewe da t
the specified intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
( Y
pag e3 15).
The brake flui dc hange interval sc an be found in
the Maintenance Booklet.
Only use brake flui da pproved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approva l3 31.0.
Information about approved brake flui dc an be
obtained at any qualified specialist workshop or
on the Internet at
http://bevo.mercedes-benz.com. i Have the brake flui dr egularl yr eplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Coolant
Important safety notes
G WARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is ar isk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clea nt he
antifreeze from components before starting
the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
coul do therwise damage the engine.
Further information on coolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact aq ualified specialist workshop.
! Always use as uitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosio na nd
overheating.
i Have the coolant regularl yr eplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
( Y
pag e3 15).
The coolant is am ixture of water and corrosion
inhibitor/antifreeze concentrate. It performs
the following tasks: R
Anti-corrosion protection R
Antifreeze protection R
Raising the boiling point
If the coolant has antifreeze protection down to
-35 ‡( -37 †), the boiling point of the coolant
during operation is approximatel y2 66 ‡
(130 †).318
